SERVICE BRAKES, HYDRAULIC
THE ROAD WAS SNOWY AND SLIPPERY, BUT NOT ICY. WHEN THE VEHICLE ABOUT 50 FEET AHEAD OF ME STOPPED FOR THE TRAFFIC LIGHT, I APPLIED THE BRAKES, BUT TO NO EFFECT. MY VEHICLE DID NOT SLOW, AND I DIDN'T HEAR THE NOISE OF THE ANTI-LOCK BRAKE SYSTEM. I CHOSE TO GO OFF THE ROAD AND HIT A PIPE RAILING RATHER THAN THE TANKER TRUCK THAT WAS STOPPED IN FRONT OF ME. OTHER VEHICLES AT THE SAME LOCATION HAD NO PROBLEM STOPPING. COPIES OF MY CORRESPONDENCE WITH TOYOTA ARE AVAILABLE. TOYOTA ONLY ROAD TESTED THE VEHICLE ON DRY PAVEMENT.

POWER TRAIN, ENGINE AND ENGINE COOLING
NO FAILURE, YET. BUT VEHICLE (LEXUS RX400H - 2006) IS A HYBRID. THERE IS A SEPARATE COOLING SYSTEM FOR THE HYBRID COMPONENTS (INVERTER, AND ELECTRIC MOTORS IN TRANSAXLE). COOLANT IS LEAKING FROM THE TRANSAXLE. IF ALL COOLANT LEAKS OUT, THE INVERTER WILL FAIL. WITHOUT THE INVERTER, THERE IS NO POWER - NO ELECTRIC STEERING, NO ELECTRIC BRAKES, AND NO MOTIVE POWER TO THE WHEELS. ADDITIONALLY, THE COOLANT MAY LEAK SOMEWHERE OR ONTO SOMETHING THAT MAY SHORT OUT OR CAUSE A FIRE. THIS IS NOT A LEAK FROM A WORN OUT COOLANT HOSE, BUT DIRECTLY FROM THE TRANSAXLE. BEING A HYBRID, THE AVAILABILITY OF ELECTRIC POWER IS ABSOLUTELY ESSENTIAL. THERE HAVE BEEN REPORTS OF INVERTERS FAILING (JUST CHECK THE LEXUS. TOYOTA AND OTHER HYBRID FORUMS) ON THE HIGHWAY AT SPEED, LEADING TO A COMPLETE LOSS OF POWER. TO THE BEST OF MY KNOWLEDGE, THERE HAVE BEEN NO INJURIES OR ACCIDENTS, BUT THE POTENTIAL IS FRIGHTENING. *TR

STRUCTURE
2006 LEXUS RX400H (AND OTHER TOYOTA/LEXUS MODELS). ANTI BACTERIAL / MOLD COATING ON A/C EVAPORATOR BEGINS SHEDDING WITH AGE/TIME AND BLOWS WHITE POWDER/DUST THROUGH VEHICLE. LEXUS SAYS IT'S ALUMINUM HYDROXIDE, AND IT'S PERFECTLY SAFE. HOW CAN IT BE SAFE TO INHALE / INGEST A FOREIGN SUBSTANCE? HAS LEXUS / TOYOTA DONE ANY STUDIES REGARDING ALUMINUM HYDROXIDE. IF IT'S SAFE, WHY DOES LEXUS / TOYOTA NOW OFFER (AND INSTALL IN NEW VEHICLES) AN A/C EVAPORATOR WITHOUT THE COATING? *TR

SERVICE BRAKES, HYDRAULIC, ELECTRONIC STABILITY CONTROL (ESC)
I WAS DRIVING MY NEW LEXUS 450H (2,000 MILES) IN A FRESH LIGHT SNOW (1.5 TO 2 INCHES) IN INCLINE VILLAGE NV AT 25 MILES PER HOUR ON A SLIGHT DECLINE WHEN I DEPRESSED THE BRAKE PEDAL TO SLOW DOWN FOR A CURVE A FEW HUNDRED FEET AWAY. IT LOCKED THE WHEELS IMMEDIATELY AND AS A RESULT I HAD NO STEERING CONTROL. GIVEN THAT I HAD ENOUGH TIME TO GET MY FOOT OFF THE BRAKE BEFORE HAVING TO MAKE TURN AHEAD, I REMOVED MY FOOT FROM THE BRAKE (I HAVE BEEN DRIVING IN SNOW MY WHOLE LIFE SINCE I WAS RAISED IN CANADA) AND IT HAD NO EFFECT -- THE WHEELS REMAINED LOCKED AS I GAINED NO CONTROL OF STEERING AND THE VEHICLE CONTINUED TO SLIDE UNTIL IT HIT THE GUARD RAIL ACROSS THE STREET AS I ENTERED THE TURN AT SOME 10 TO 15 MILES AN HOUR. I AM CONVINCED THAT THE PROBLEM LIES IN THE 450H TRYING TO GENERATE POWER WHENEVER THE GAS PEDAL IS NOT DEPRESSED -- THIS IS DIFFERENT THAN MY FORMER LEXUS 400H WHICH ONLY TRIED TO GENERATE POWER WHEN THE BRAKE PEDAL IS DEPRESSED (I KNOW ABOUT THE NEW LOGIC BECAUSE THE POWER GAUGE (THAT SHOWS WHETHER THE BATTERIES ARE CHARGING OR DISCHARGING) SHOWS CHARGING WHENEVER ONE'S FOOT IS TAKEN OFF THE GAS PEDAL ON THE 450H, NOT ON THE 400H). NEEDLESS TO SAY, I IMMEDIATELY WENT TO THE LOCAL LEXUS DEALER AND TRADED THE VEHICLE FOR AN RX350 THAT WILL DRIVE LIKE A NORMAL CAR. I AM ONLY INTERESTED IN HAVING PEOPLE THAT LIVE IN HILLY SNOW CONDITIONS AVOID BUYING THE RX450H AS THEY WILL NECESSARILY HAVE THE SAME EXPERIENCE. I DO NOT HAVE VIN AT THIS TIME AS I AM AT MY SECOND HOME IN CALIFORNIA AT THIS TIME. *TR

TIRES
THE 2006 LEXUS RX400H HAS CONTINUOUSLY DEMONSTRATED EXTREMELY EXCESSIVE INSIDE FRONT TIRE WEAR. THE ORIGINAL FACTORY TIRES WERE REPORTED AS WORN OUT AT A 10K MILE DEALER INSPECTION, AND THAT IS AFTER AN INSPECTION AT 5K MILES BROUGHT NO PROBLEMS TO MY ATTENTION. AFTER APPROXIMATELY 50K MILES, ON THE THIRD SET OF TIRES, WITH REPEATED ATTEMPTS TO ALIGN THE FRONT END AND RESOLVE THE PROBLEM, THE ISSUE APPEARS TO REMAIN. THIS VEHICLE DESTROYS FRONT TIRES AT A RATE THAT WILL TAKE CONSUMERS BY EXTREME SURPRISE AND COULD RESULT IN SERIOUS TRAFFIC INCIDENTS DUE TO FRONT TIRE FAILURE. TIRES WITH A LOWER SPEED RATING DO SEEM TO IMPROVE LIFE, AS I HAVE SEEN IN THE LAST SET OF TIRES (EACH SET TRIED HAS BEEN DIFFERENT MANUFACTURER WITH HIGHER LIFE RATINGS); HOWEVER IT DOES NOT RESOLVE THE ISSUE SINCE THE LIFE OF THE TIRES IS STILL BEING DEMONSTRATED TO BE WELL LESS THAN HALF THAT EXPECTED. *TR

ELECTRICAL SYSTEM
DEAD STARTER BATTERY - 1. SINCE THE VEHICLE WAS NEW (WE ARE ORIGINAL OWNERS) THE STARTER BATTERY WOULD BE DEAD IF WE DID NOT DRIVE THE CAR FOR 4 OR MORE DAYS (OBVIOUSLY NOT BEING ABLE TO TAKE IT ANYWHERE WHERE IT WOULD SIT WITHOUT A CHARGER NEARBY LIKE TO AN AIRPORT). LEXUS HAS REPLACED THE BATTERY 3 TIMES BUT JUST 1 MONTH AGO REPLACED IT AGAIN AND NOW AFTER A 1 WEEK TRIP TO CANCUN BATTERY WAS DEAD AGAIN. LEXUS PRETENDS TO NOT UNDERSTAND THE PROBLEM BUT MANY PEOPLE COMPLAIN OF THIS SAME PROBLEM THAT IS OFTEN MUCH WORSE WHERE THE CAR SHUTS DOWN WHEN DRIVING. MANY PEOPLE THAT HAVE HAD THIS SAME SERIES OF PROBLEMS ULTIMATELY NEED TO HAVE THE INVERTER REPLACED WHICH IS A $9K PLUS PART (SO FAR IT SEEMS WHEN ITS PROVED TO LEXUS THEY DO THIS AT NO CHARGE -- BUT MINE IS NOW OUT OF WARRANTY). 2. PROBLEM ALWAYS OCCURS IF THE CAR SITS WITHOUT BEING STARTED FOR MORE THAN 4 DAYS. 3. THEY HAVE REPLACED BATTERY 3 TIMES. WE ARE AFRAID THAT OUR PROBLEM WILL ESCALATE AND MY WIFE WILL BE DRIVING WITH OUR 8 & 10 YEAR OLD CHILDREN AND THE BATTERY SYSTEM WILL FAIL CAUSING THE ENTIRE CAR TO SHUT DOWN AND SHE IS NOT STRONG ENOUGH TO STEER TO SAFETY WHEN BRAKE AND STEERING ARE NOT WORKING. IT IS UNFAIR FOR US TO POTENTIALLY HAVE TO SELL THE VEHICLE AT A HUGE LOSS TO AVOID THIS POTENTIAL ISSUE (AND THEN SOMEONE ELSE WILL HAVE THE PROBLEM). *TR

STEERING
I HAVE 2007 LEXUS 400H AND THE VEHICLE DRIFTS WHEN IT CATCHES EITHER A ROAD CRACK WHEN CHANGING LANES OR ON CERTAIN ROADS WHERE THERE IS A SMALL CROWN. THE STEERING GET TIGHT ON CORRECTING IT DRIFTS TO THE OTHER SIDE. STEERING ALSO GIVES A TUG OR A WOBBLE TO WHEN HITTING CERTAIN CRACKS OR BUMPS. THE DRIFT AND TUGS GENERALLY ARE TO THE RIGHT. DEALER SAYS EVERYTHING LOOKS GOOD AND BLAMES IN ON TIRES. MY MICHELIN TIRES WITH TREADWEAR 450 ARE ALMOST WORN AT 25,000 MILES. I FEAR DURING SNOW THIS WILL BE DANGEROUS. *TR

STEERING
WE BOUGHT A LEXUS 450H 3 MONTH AGO. ON LAST SATURDAY, WHEN THE CAR HIT CURB AT STARTING SPEED, THE STEER WHEEL TURNS 90 DEGREE. THE LEFT FRONT TIRE HAS ONLY VERY SMALL IMPACT, SOME DUST MARK CAN BE EASILY WIPED OFF. THE CAR IS STILL DRIVABLE, BUT WE ARE AFRAID THAT THIS CAR MAY LOSS CONTROL VERY EASILY, ESPECIALLY WHEN IT IS OFF ROAD ON BUMPY ROAD. DEALER IS STILL TALKING WITH THE FACTORY TO CHECK WHETHER THE FACTORY WARRANTY WILL COVER THE DAMAGE. *TR

STEERING
WHILE TURNING INTO PARKING LOT FROM ROAD BUMPED THE RIGHT FRONT TIRE INTO CURB AT APPROX 4 MPH. POWER STEERING IMMEDIATELY CEASED TO FUNCTION. TOLD BY TOYOTA MECHANIC THAT A HIGH VOLTAGE POWER SPIKE DESTROYED THE POWER STEERING COMPUTER. PAID $1050 FOR REPLACEMENT OF POWER STEERING COMPUTER. DOES THIS MEAN A POTHOLE CAN ALSO FRY THE P/S COMPUTER. *TR

ELECTRICAL SYSTEM
WHILE DRIVING A 2006 LEXUS 400H THE ENGINE, POWER STEERING, LIGHTS, EVERYTHING! JUST QUIT AND THE CAR HAD TO BE MANEUVERED OFF THE ROAD WITH NO POWER WHAT SO EVER. IT WAS VERY DANGEROUS. THE CAR'S INVERTER HAD FAILED. THIS CAR HAS BEEN MAINTAINED AND SERVICED BY THE DEALER FOR ITS ENTIRE LIFE AND HAS HAD NO INDICATION OF A PROBLEM PRIOR TO THE FAILURE. THE NEW INVERTER COSTS $8300! WE WILL PROBABLY SELL THE CAR FOR SALVAGE AS ITS WAY TOO MUCH MONEY AND WHO KNOWS WHAT WILL GO OUT NEXT! APPARENTLY THIS FAILURE HAS OCCURRED IN OTHER HYBRIDS BY LEXUS AND TOYOTA. ITS A MIRACLE THAT THERE WAS NOT AN ACCIDENT WHEN THE ENGINE FAILED. *TR
